We are using a third party solution, Plimus, for credit card clearing in our company.

It looks like many credit cards, specially local ones, specially in countries like Brazil, are being denied.

We are unable to receive a list of supported credit card types, as it seems that the list doesn't really exist anywhere... can this be true? That the only way for a payment gateway\processor to know whether it can support the transaction or not is buy trying? And then it is for the local bank to decide whether to authorize it or not?
